Dealbreakers: 5 Unexpected Habits That Lead To Breakups

We all have our dating dealbreakers. From bad hygiene to a low credit score, the list goes on (and sometimes, on). But what about those breakup worthy traits your partner has when you're already in a relationship?

According to a study by SKYCIG, 55 percent of women would leave their man over little annoyances and habits. What behavior, aside from the obvious offenders, like lying and cheating, is just so irritating that you'd call it quits?

Take a look at the list below of the most annoying habits that ruin relationships and tell us your thoughts in the comments.

1. Smoking
A big dealbreaker for people before they get into relationships, smoking is also one — the biggest one — for people who are already in relationships. Remember in Sex And The City when Aidan found out Carrie was sneaking cigarettes and accused her of "cheating" on him? Well, technically she was having an affair, but regardless, her smoking addiction was a big enough issue that he made her promise she'd quit or he couldn't be with her. And he's not alone. Sixty-four percent of men and women agree: The smell of smoke and watching their loved one harm their health every day is the top breakup-worthy habit.

2. Never Listening
What'd you say? After smoking, not listening came in as the second biggest dealbreaker for couples. It's a bad habit that affects how both of you behave. How can you really communicate if you're not paying attention to the other person?

3. Poor Money Management
You've heard "it's not the size of the boat, it's the motion of the ocean" before. Well, the same principle applies for 22 percent of people, who said poor money managment is a reason to call it quits. And, it makes sense, too. Contrary to popular belief, women aren't looking for splurgers. How you handle your money says a lot about how much self-control you have — and you handle other things in your life. Plus, there's new research to back it up: money savers are actually sexier than spenders.

4. Laziness
Would you end it with your significant other for being a couch potato? Nineteen percent of people surveyed would. Like many other traits, lacking motivation and ambition extends into other areas of your partner's life — and yours.

5. Hogging The Remote
Here's a shocking one. For 15 percent of people, ownership over the TV is their partner's most irritating habit. Sure, it's annoying, but it seems like an easy fix. No one wants the Real Housewives to come between their relationship.

1. Margaret Cho + Al Ridenour

2. Hugh Hefner + His Girlfriends

2. Hugh Hefner + His Girlfriends: Hef will never truly settle down, no matter what his station or status. Remember, Holly Madison and Kendra Wilkinson have careers because of their three-way open relationship with Hef and Bridget Marquardt.

3. Rachael Ray + John Cusimano

3. Rachael Ray + John Cusimano: The cooking queen and her musician hubby have denied the open-ness of their marriage, saying it's insulting to their families. But he was reportedly a patron at Checkmate, a swinger's club.

4. Robin Thicke + Paula Patton

4. Paula Patton + Robin Thicke: The "Blurred Lines" singer was asked about the nature of his relationshp during a Howard Stern show interview, but chose not to answer out of respect for his actress wife. Then, the marriage eventually imploded and he groveled to "get her back." It didn't work.

7. Brian Austin Green + Megan Fox

5. Megan Fox + Brian Austin Green: This sounds like an odd set up if it were indeed true. Word is that Green was not allowed to see anyone else, but Fox had permission to date other dudes. We cannot help but wonder if that arrangement has changed since they had two sons and since her career has cooled.

6. Tilda Swinton

6. Tilda Swinton + John Byrne: The unmarried duo has twins, but she has said that they both enjoy the company of others while remaining close. "It may seem odd but it is certainly the best thing for the children," the actress said. "It's not something I try to promote as a radical lifestyle choice. But it's a situation I find very healthy. I can maintain my life with my children and their father and spend time with the man I've become very fond of. I am very fortunate there has been a lot of understanding by the men." Progressive, indeed.

8. Will Smith and Jada Pinkett Smith

8. Will Smith + Jada Pinkett Smith: These long-married parents of two have spoken about the concept of love not being akin to ownership and there have been rumors that each may have strayed with others ... but that's only if you look at it as straying.

9. Dolly Parton + Carl Dean

9. Dolly Parton + Carl Dean: The voluptuous country singer has been married to her hubby since 1966. She has spoken about not wanting to know if any cheating is happening and has said if they do cheat and don't know about it, that's probably why their marriage works. Interesting theory.... sort of.

10. Mo'Nique + Sidney Hicks

10. Mo'Nique + Sidney Hicks: The Oscar-winning actress and her husband are BFFs and have known each other 25 years. Mo'Nique has said she would not end the marriage if he cheated and she also said that while they have an open relationship, she does not practice the open door policy. We are left to believe that perhaps it is he that does.
